Produce a migration assessment for five real workloads

applied · 75 min · Objective 2.1

Task

Apply the whole of objective 2.1: for five workloads you actually know, produce the sizing, the dependency map, the compatibility position and the licence consequence -- and reach an honest disposition for each, including the ones that should not move.

Steps

  1. Build lab/assessment.csv with one row per workload and columns workload,binding_metric,target_size,dependencies,blockers,licence_model,disposition,evidence_quality.
  2. For dependencies, state how you would OBSERVE them rather than ask -- flow logs, connection tables, configuration search -- and note the observation period needed to catch a monthly job.
  3. For at least one workload, find a genuine blocker from the lesson's list: a dongle, MAC-bound licensing, specialist hardware, multicast, or an unsupported version the vendor will not certify.
  4. For at least one workload, work out whether a resize would change the licence cost, and by how much.
  5. Reach a disposition for each -- rehost, replatform, refactor, repurchase, retire or retain -- and for any RETAIN write the specific reason and what would have to change for the answer to differ.

Verify

awk -F, 'NR>1 && NF>=8 {n++} END {print n" assessed workload(s)"}' lab/assessment.csv
awk -F, 'NR>1 {print $7}' lab/assessment.csv | sort -u | wc -l
grep -Eci 'dongle|mac|multicast|unsupported|hardware' lab/assessment.csv
grep -Eci 'retain' lab/assessment.csv

Five workloads, at least three distinct dispositions, and at least one retain with a specific reason. An assessment where everything moves has not looked hard enough.
